Features of React JS that make it a favored choice

The technology landscape for frontend development has been evolving at a rapid pace, with new tools, frameworks, and libraries being introduced almost daily. This constantly emerging innovation provides developers with a rich selection of options, but it also poses a challenge for marketers and entrepreneurs who must navigate this complex environment to choose the most suitable technologies for their projects.

Amidst this ever-expanding array of choices, React JS stands out as one of the most popular and widely adopted frontend development frameworks. Its efficiency, flexibility, and robust ecosystem make it a preferred choice for creating dynamic and responsive user interfaces. 

What is React JS? 

React JS is a powerful and versatile open-source JavaScript library created and maintained by Facebook. It is designed to build user interfaces, particularly for single-page applications where a fast and responsive user experience is crucial. React’s efficiency comes from its ability to update and render components swiftly, making it an ideal choice for developing front-ends of web applications that are not only simple but also highly performant and scalable.

In a survey conducted by Stack Overflow, React emerged as the most popular framework for frontend development, securing the number one position. This popularity is reflected in its widespread adoption across the web.

Currently, over 220,000 websites leverage React for their front-end development needs. This includes some of the world’s leading companies such as Apple, BBC, PayPal, and Netflix, all of which use React to deliver seamless and dynamic user experiences on their platforms.

Features of React JS that make it stand out

Before diving into why React is so popular, let’s explore its key features. Understanding these features will provide insight into how React JS works.

Features of React JS that make it stand out

Virtual DOM:  

One of React’s standout features is the Virtual DOM, which enhances the speed and flexibility during React JS development. The Virtual DOM creates a virtual representation of the actual DOM in React’s memory.

When the application undergoes changes or updates, the Virtual DOM re-renders the entire UI, but only updates the components that have been modified. This selective updating process significantly reduces the React JS development time and cost.

JavaScript XML (JSX):

JSX, or JavaScript XML, is a syntax extension for JavaScript that allows developers to write code that closely resembles HTML. This markup syntax is used to describe what the user interface should look like, making it more intuitive for developers to create React components.

One of the key advantages of JSX is that it simplifies the process of building the user interface. By allowing developers to write HTML-like code within JavaScript, JSX streamlines the creation of complex UI elements and enhances code readability. This ease of use and the ability to visualise the component structure directly within the code make JSX one of the most appreciated features of React JS, enabling developers to efficiently construct the building blocks of their applications.

React Native: 

React Native is a framework that extends React JS to mobile development, allowing developers to build native applications for Android and iOS using React. Instead of relying on web components, React Native uses native components, which means the applications can take full advantage of the native features and capabilities of the mobile platforms.

Essentially, React Native transforms React code so that it can be rendered on iOS and Android devices. This feature enables developers to create mobile apps that are truly native in look and feel while maintaining the efficiency and component-based architecture of React.

One-Way Data Binding: 

React employs a unidirectional data flow, known as one-way data binding. This approach means that data flows in a single direction, from parent to child components, ensuring that changes in the data always follow a predictable pattern.

To modify the state or data of a component, developers must use callback functions rather than making changes directly. This mechanism prevents direct manipulation of components, thereby enhancing the robustness of the application.

Control over the data flow is managed using Flux, a JavaScript architecture that complements React. Flux provides a structured way to handle data, giving developers better control over the state and flow of the application, ultimately making it more flexible and efficient.

Declarative UI:

The declarative UI feature in React makes the code more readable and easier to debug. By allowing developers to describe what the user interface should look like at any given time, React abstracts away the complexities of managing UI states. This approach ensures that the UI is consistently in sync with the underlying state, reducing the likelihood of bugs and making the React JS development process more intuitive.

React JS excels in creating dynamic and engaging user interfaces not only for web applications but also for mobile applications. Its declarative nature simplifies the process of developing UIs that are both exciting and user-friendly.

Component-Based Architecture: 

React JS employs a component-based architecture, meaning that the user interface of an application is built using a collection of reusable components. Each component encapsulates its own logic and structure, written in JavaScript.

This modular approach allows developers to manage and pass data throughout the application without directly affecting the DOM. Components in React are crucial for defining the visual aspects and interactions within the app. They enable developers to build complex UIs by combining simple, isolated pieces of code, making the React JS development process more efficient and maintainable.

Advantages of using React JS

React JS has gained immense popularity due to its numerous advantages, making it a preferred choice for web and mobile app development:

Short Learning Curve:

React JS boasts a remarkably short learning curve compared to other frameworks, making it highly accessible to developers. This ease of learning accelerates the React JS development process, allowing developers to swiftly master React and complete projects in record time. Businesses can leverage this advantage to establish their online presence quickly and efficiently.

Enables Building Rich UI:

In today’s digital landscape, the user interface (UI) plays a pivotal role in determining the success of an application. Apps with captivating UIs that provide users with engaging browsing and shopping experiences have a competitive edge over those with lackluster interfaces.

React JS enables developers to create rich and interactive user interfaces with ease. Leveraging its declarative components feature, developers can build engaging interfaces of superior quality. This capability not only enhances the user experience but also contributes to the overall success and adoption of the application.

Facilitates Creation of Custom Components:

One of the standout advantages of React JS is its facilitation of creating custom components tailored to specific project requirements.

JSX: React’s JSX syntax allows developers to craft unique components seamlessly by combining JavaScript with HTML-like syntax. This approach simplifies the creation of custom components and streamlines the rendering of sub-components within the application.

Additionally, React enables the development of high-volume applications by efficiently generating React Element trees from HTML mockups, enhancing scalability and performance.

Boosts Developer Productivity:

React’s component-based architecture significantly boosts developer productivity by promoting component reuse and modularity.

Component Reusability: By encapsulating functionality within reusable components, React enables developers to efficiently distribute digital objects across various parts of the application. This reusability minimises redundant code and simplifies maintenance and updates, even when modifications to components may impact others.

Component Composition: Developers can easily compose complex UIs by combining simple elements and arranging them within wrapper components and root elements. This modular approach not only enhances code maintainability and scalability but also fosters better organisation and management of the codebase.

The inherent logic encapsulated within each React component ensures clear separation of concerns and facilitates granular control over the application’s behavior, ultimately leading to improved code maintainability and extensibility.

Quick Rendering:

Ensuring rapid rendering is crucial, especially for complex and high-load applications where the app structure must be meticulously defined from the outset.

React’s virtual DOM feature proves invaluable in this regard. Conceptually, the DOM structure resembles a tree, wherein even a minor edit made at the top-level layer can significantly impact the app’s UI. Here, the virtual DOM serves as a safeguard, allowing all changes to be initially tested within it to assess the risk level associated with each modification before finalising it.

By leveraging the virtual DOM, developers can meticulously optimise the app’s performance and guarantee a superior user experience. This iterative approach not only enhances the efficiency of React JS development but also ensures that the app maintains high performance standards even under heavy loads.


Search engine optimisation (SEO) is paramount for the success of any application, and two critical factors for optimising apps are fast load times and efficient rendering.

React’s super-fast rendering capability dramatically reduces page load times, thereby enhancing the app’s SEO performance. By minimising load times, businesses can improve their app’s ranking on Google search result pages, increasing visibility and driving organic traffic to their applications. This SEO-friendly feature of React enables businesses to enhance their online presence and attract a wider audience base.

Helpful Developer Toolset:

Within the React JS framework, Facebook has incorporated a robust set of developer tools designed to streamline the React JS development process. These tools, seamlessly integrated with React and Chrome, provide developers with invaluable insights into the application’s structure and state.

Component Inspection: Developers can leverage these tools to effortlessly discover parent and child components, observe their hierarchical relationships, and inspect their current state. This level of visibility enhances developer productivity by facilitating efficient debugging and troubleshooting.

Furthermore, through continuous self-learning and exploration of emerging technologies, developers can effectively apply their newfound knowledge to real-world projects, further refining their skills and enhancing the quality of their work.

Enhanced Code Stability:

React JS ensures enhanced code stability through its downward data flow mechanism. This architectural approach ensures that changes made to child components do not impact the parent structure.

By manipulating component states to effect changes, developers can update specific components without affecting others. This granular control over state management minimises unintended side effects and ensures that the application’s codebase remains stable and maintainable.

As a result, React-based applications exhibit smooth performance, offering users a seamless and uninterrupted experience. This enhanced code stability contributes to the overall reliability and robustness of React JS applications, making them well-suited for building scalable and resilient software solutions.
